MOTQR-VEHICLE.

Specification of Letters Patent.

Patented Oct. 10, 1916.

To all whomz't may concern Be it known that I, MILTON TIBBETTS, a

' citizen of the United States, and resident of Detroit, iVayne county. State of Michigan,

have invented certain new and useful Im- PlQ VGIIlBIllZS in Motor-Vehicles, of which the folowi'ug is a specification. I

This invention relates to motor vehicles,

and. particularly to the road wheels, their 1n n'iounting on the axle, and the indicator driving mechanism which is driven by the road wheels for indicating the speed or distance traveled.

One of the foremost objects of the invention is the production of a suitable driving mechanism for an indicator, such as a speed omcter or odometer, in conection with a road wheel that has its hub formed with a spindle which extends inwardly and is mounted in a hollow suporting member.

Other objects of the invention will be apparent from the following description, taken in connection with the drawings, which form a part of this specification, and in which,

Figure 1 is a vertical section through one of-the front steering wheels of a motor vehicle, and the contiguous parts of the axle; Fig. 2 is an external end view of the cap arranged on the wheel support; and Fig. 3 is an internal end view of said cap with parts broken away.

Referring to the drawings, 10 represents one of the ends of an axle of a motor vehicle, which end is branched, and between the arms 85 11 of which is arranged a wheel support 12. The wheel support is preferably of barrel shape, having integral trunnions 13,which are adapted to oscillate in bushings 14 secured in the ends of the arms 11 by removable caps 1.5. One of these caps 15 is shown in section in, Fig. 1, and the other cap is shown in elevation, and bolts 16 are shown as holding the caps in position.

A vehicle wheel 17 is shown as formed as with a hub member 1-8, to which the spokes 1.9 are secured, and said hub has an integral or otherwise formed spindle 20, which extends inwardly and is supported in a pair of separated roller bearings 21 and 22 in the wheel support 12. These bearings are of such form that one of them takes the thrust in one direction and the other in the other .direction', and they are secured in place on p, the spindle 20 by asecuring nut 23, which is wthreaded on the inner end of the spindle.

A ring 24 separates the bearings on the spindle, and a washer 25 forms an abutment for the bearings at the outer end of the spindle. This washer is also surrounded by a packing ring 26, which prevents the escape of lubricant and the ingress of dust .or dirt. The inner end of the wheel support or barrel 12 is covered by a bracket or cap 27 which is secured to the support- 12 by a series of bolts 28, these bolts being three in number in the embodiment of the invention shown. i

, Mounted in bearings 29 in the cap 27 and dash or other part of the vehicle, and is operatively connected to the shaft 32 by.

means of a flexible shaft of suitable design.

The worm wheel 30 is arranged to be.

driven by the spindle 20 as it rotates, and in the drawing this is shown as a direct connection, a squared extension 33 of the axle of the wheel'30 entering a squared opening 34 'in the inner end ofthe spindle 20; This connection need not be a very close fit, and in fact should be loose enough to allow for any slight error in machining that may occur in manufacture.

lVhile a specific embodiment of" the invention has been described in detail, which embodiment is deemed to be new and advantageous and will be specifically claimed, yet

it will be understood that the invention 1s not limited to the exact construction shown, as it will be apparent that changes may be made without departing from the spirit and scope of the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1 In a motor vehicle, the combination with the axle, a wheel support pivoted to the axle and comprising a hollow member, and a wheel having a, supporting spindle rotatably mounted in said support, of an indicator driving mechanism connected with said spindle, and having a driven shaft leading therefromand adapted to drive an indicator.

2.11; a motor vehicle, the, combination with the axle, a wheel support pivoted to the axle and comprising a hollow member,

and a wheel having, a supporting spindle rotatably mounted in said support, of an indicator driving mechanism mounted on said support and having a driving connecjtion with saidvspi ndle, and adriven shaft leading from-,the mechanism," said driven shaft'beingfadapted to drive an indicator. I

-3. In a motor vehicle, the combinatlon with theaxl e, a wheel support pivoted to the axle and comprising a hollow member,

and a wheel having a supporting spindle rotatably mounted in said support, of a cap for closing the inner end of said support, an indicator driving mechanism mounted in said cap, and a driving connection from said spindle to said mechanism.

. 4. In a motor vehicle, the combination withth'e axle thereof, of a cylindrical wheel support having substantially vertical trun: nions in said axle, a wheel having a supporting spindle extending into said support, bearings'between said spindle and said support, an indicator driving mechanism mounted on said support, a driving connection between said spindle and said mecha- T 5. In a motor vehicle, the combination with the axle thereof, of a cylindrical wheel support having substantially vertical trunnions 111 said axle, a wheel having a sup-' porting s indle extending into said support,

the axle and comprising a hollow member,

and a wheel having a supporting spindle rotatably mounted in said support, of a cap for closing the inner end of said support, an indicator driving-mechanism mounted in said cap, and including a shaft passing out wardly through-the cap, and a driving connection from said spindle to said mechanism.

In testimony whereofl afiix my signa} lure in the presence of two witnesses.
